It is one of the technical problems that must be considered in the construction of the comprehensive pipe gallery to put an end to the phenomenon that the pipeline has been soaked in the leakage water for a long time and solve the waterproof problem well It can effectively solve the waterproof problem so as to ensure the construction quality of the comprehensive pipe gallery It can also fundamentally reduce the potential safety hazards, reduce the later operation and maintenance costs, and extend the service life of the pipe gallery The waterproof grade shall be determined according to the pipeline type of the specific pipe gallery If there are important lines such as high-voltage cable, weak current and communication transmission entering the pipe gallery, and moisture and leakage are likely to cause corrosion and ignition of the connecting parts, the waterproof layer shall be grade I waterproof, and these lines shall also be separately set up "In the construction, the underground water and surface water conditions of the city where the pipe gallery is located should be considered For example, in the city where the surface water drainage is not smooth, even if the underground water level is very low, the first-class waterproofing should be done If the area with rich underground water content, the first-class waterproofing is more stable." Some experts said that "at present, the secondary waterproofing in the technical specifications for urban comprehensive pipe gallery engineering should be adjusted to be no less than the secondary level, which should be more appropriate." Underground pipe gallery is not a new thing, waterproof engineering is also a commonplace But only if we do a good job in waterproofing can we ensure that the underground pipe gallery will become a century old project and promote the healthy and orderly development of the whole city More importantly, the waterproof industry should also take advantage of the rare opportunity brought by the construction of underground pipe gallery, increase innovation and standardization in materials, technology and construction, and then promote the transformation and development of the whole industry Wqbz type inflatable cable duct is widely used for waterproof sealing of underground cable duct, high-voltage cable, weak current and communication transmission pipeline to effectively prevent water, sediment, insects, rats, harmful gases and other substances from entering the pipeline The national inflatable pipe waterproof sealing product produced by Zhuzhou complete science and Technology Co., Ltd is the core component of the product "inflatable pipe plug", which is a sealed air bag made of polymer aluminum foil composite material The sealing effect of the pipe hole is realized by the principle of inflatable expansion Two sides of the inflation pipe plug are pasted with waterproof rubber strip When the product is inflated to 2.6-2.8kg air pressure, the gap between the pipe, the inflation pipe plug and the cable is well filled to achieve the complete sealing effect Silica gel material is installed on the inner side of the gas filling hole of the gas filling pipe plug When the gas filling is completed and the gas filling pipe is pulled out, the self filling performance of silica gel material can block the gas filling hole to ensure that the gas does not leak The application characteristics of inflatable cable duct plugging airbag products are as follows: 1 It can meet the needs of air duct, multiple cables passing through a single pipe, etc 2 The sealing effect is good After sealing at both ends, the water, sediment, harmful gas, insects and rats in the pipeline can be completely isolated and kept dry and clean 3 The installation conditions are low, and various gas sources can be selected independently; the installation is fast, and the operation can be completed by one person; the removal of later maintenance is simple, without damaging the cable and pipe wall 4 After the correct installation, the service life is up to 20 years without human damage 5 Wide working temperature difference (-15 ℃ - 60 ℃), strong resistance to acid and alkali corrosion of underground water, and able to withstand the cable axial tension and low-frequency vibration 6 Scope of application: it is mainly used for plugging underground pipe network and cable pipe holes of electric power, communication, urban construction and urban rail transit, and for plugging through wall holes of underground civil engineering walls in commercial and residential communities; it is suitable for pipes of rigid materials such as plastic, steel, cement, etc.; it is suitable for round or oval sealing holes 7 The product has certain fire-retardant effect 8 Secondary installation and utilization can be realized according to the needs of customers If the air filled pipeline waterproof plugging product is used as early as possible in the urban power underground pipe network, it can effectively improve the cable protection level and operation safety factor in the pipeline, and avoid the large amount of capital and manpower invested in dredging repeatedly in the later stage It will not affect the later cable laying and replacement Warm tip: This is a network reprint from the waterproof enterprise network Zhuzhou complete science and Technology Co., Ltd is an expert in power pipeline plugging It aims to spread more industry information and invade and delete!
